Specificatioaof Letters Patent. PatentedAug. 23, 1921- Applicatlon filed September 8, 1919. Serial No. 322,322.

. To all whom it may concern:

Be it known thatI, HENRY P. UMBsEN a cltizen of the United States, residing at San Francisco, in the county of San Franoisco and State of California, have invented new and useful Improvements in Devices for Treating the Eyes, of which thefollowing is a specification.

The present invention relates to an improved apparatus for medicinally treating the eyes with liquids such as water containing boric acid or plain water ofany desired temperature.

In the accompanying drawing, Figure 1 is a front view of my improved apparatus; Fig. 2 is a broken rear view thereof; Fig.

3 is a side view thereof; Fig. 4 is alongitudinal section thereof; Fig. 5 is a broken longitudinal section thereof on the line 55 of Fig. 2; Fig. 6 is a plan view thereof on a reduced scale Fig. 7 is a detail sectional view of a modification. 1

Referring to the drawing, 1 indicates a casing formed of any suitable material, as glass, closed at the front side and open at the rear sides, and the rear edge of which is conformed to fit closely against the forehead and nose of the patient. Into said casing is inserted a chamber 2 of hard rubber or any other suitable material. Said chamber comprises on each side an annular compartment 3, having a circular opening thereholes in the bottom of the central compartment and easing 1 a valve casing 7 communicating at the bottom with ports 8 and conduits 9 communicating at the bottom with hard rubber nipples 11, on which can be attached rubber tubes leading from sources of supply of hot and cold water respectively or of any medicated liquid desired. The flow of liquid through said valve casing is controlled by a rotary hollow valve 12 extending through said valve casing 7 to the front thereof and being there provided with a handle 13 for turning said valve to permit more or less cold or hot water or medicated liquid, as desired, to enter said hollow valve. Said valve is secured in place by a nut 14 screwed on its rear end and at the top communicates by a port 16 with a port 17 in the valve casing, communicating with the central'compartment 6, from which the water fiowsinto the side compartment 3. From said side compartments, the water flows through small perforations 18 in their rear walls 19 and impinges upon the face of the patient around his eyes and escapes from said casing 1 by hard rubber nipples 24, to whichmay be attached drain tubes 26. The maximum extent to which the valve can be turned to admit any desired liquid therethrough can be regulated by moving a spring stop'27, which can be sprung into any one of the recesses in a circular rack 28. Said stop has a finger 29 against which the handle 17 impinges when it is rotated.

The device is held against the face of the patient by a ribbon or other band 31 secured to eyes 32formed in the side walls of the casing 1.

Fig. 7 indicates a modification of the invention, showing a means for making a tight joint between the rear edge of the casing 1 and the face of the patient. Said rear edge is formed with an enlargement 83, around which is passed a grooved extension 34 from a rubber tube 36, the grooved extension 34 being given a certain degree of hardness by vulcanization while the rubber tube 36 remains soft.

1. In a device for treatment of the eyes,

the combination of a casing closed at the ":7 I front side and, open at the rear side, and oi.

a form to fit closely against the face of the patient around the eyes, annular chambers in said casing having discharge openings in their rear walls, means for admitting a;

"stream of liquid intosaid chambers, and

means for directing the flow of liquid from said casing.

2. In a device for treatment of the eyes, the combination ofa casing, closed at the front side and open at the rear side, and of a form to fit closely against the face of the patient around the eyes, means for separately supplying different liquids to said casing, and means for directing a stream of the liquid from said casing.

3. In a device for treatment of the eyes, the combination of a casing, closed at the front side and open at the rear side, and of a form to fit closely against the face of the patient around the eyes, a chamber in said casing having perforations in its rear wall,

means for admitting a stream of liquid into said chamber, means for guiding a stream "of li uid flowing from said casing in the rear of said. chamber, and transparent portions in g the front side of'the casing.

the combination of a casing, closed at the front side and open at the rear side, and of a form to fit closely againstthe face of the patient around the eyes, a chamber insaid casing having perforations in its rear wall,

-means for admitting a plurality of streams of different kinds of liquid into said chamber, .means for guiding a stream of liquid from said casing in the rear of said chamber.

5. In a device for treatment of the eyes,

the combination of a casing,-.closed at the frontside and open at the rear side, and of a form to fit closely against theface of the patientnround theeyes, a chamber in said casing having perforationsin its rear wall, means for admi ttinga plurality of streams of liquid into said chamber, means for varying theproportions of the streams of liquid admitted into said chamber, and means for guiding a stream-of liquid from said casing in the rear of said chamber, 7

" 6. In a device for treatment of the eyes, the combination of a glass casing, closed at the front side and open at-the' rear side and of'a form to fit closely against the-face of the patient around the eyes, an annular chamber in said casing having perforations in its rear wall, means for admitting a plurality of streams of. liquid into'said chamber and means for guiding a stream of liquid from said'c'asi-ng-inrthe rear of said chamber.

7. Ina device for treatment of the eyes, the combination of a casing, closed at the front side and open at the rearside and of a form to fit closely against the face of the patient around the eyes, a chamber in said said first-named port and with the lastnamed 1 port respectively, and means for guiding a stream of liquid from said casing in the rear of-said chamber. 1

' 8. In a device for treatment ofthe eyes,

the combination of a casing, closed at the front-side and open at the rear side and of a form to fit closely against the face of the patient around the eyes, a chamber in said casing having perforations in its rear wall,

"a valve casing having ports therethrough 4. In a device for treatment of the eyes,

ports therethrough' adapted to communicate with said first-named ort and with the lastnamed port respective y, a handle for moving said rotary valve and a stop for said handle limiting its movement, and means for guiding a stream of liquidfrom said casing in the rear of said chamber.

9. In a device fortreatment of the eyes,
